Bits A10–A17 must be set to all ‘0’. 2. BL=8 is not available for configuration 1 and 4. 3. ±30% temperature variation. 4. Within 15%. Remark The address A0, A3, A4, A5, A8, and A9 must be set as follows in order to activate the mode register in the multiplexed address mode. Figure 2-28. Power-Up Sequence in Multiplexed Address Mode Notes 1. Recommended all address pins held LOW during dummy MRS command. 2. A10-A17 must be LOW. 3. Address A5 must be set HIGH (muxed address mode setting when µPD48576209/18/36F1 is in normal mode of operation). 4. Address A5 must be set HIGH (muxed address mode setting when µPD48576209/18/36F1 is already in muxed address mode).
